I'm wondering if some you who have been winding coils for much longer than I have, might know what causes hot spots on coils which in turn causes severe juice explosions. You know those pops that put your front teeth in danger... Is there a way to avoid these and also is there a way other than rewinding to correct the issue?

Pre torching can help i use my gas stovetop if your wrapping macros with the wires touching then pulse, squeeze, repeat till you get it glowing evenly and no hotspots in legs (all this without a wick in lol)
Also a very common cause of hotspots and hot legs are loose connection screw, most screws tend to back out after initial heating, fRom the wire expanding, now all this is mostly relevant if your talking about rda/rba
Hope this helps

Just sounds like popping juice to me, "hot spot" generally refers to an actual short, either between wraps or between wraps and wick (on genesis devices with stainless steel mesh wicks) which cause erratic resistance readings and horrible flavor.
As far as what causes juice to pop, I believe it's similar to how you sometimes get tiny grease explosions when frying bacon. A small bit of moisture is superheated and instantly turns into vapor, which expands rapidly shooting whatever liquid present in all directions. Or how you can have exploding water if you microwave it to boiling temperature in a really smooth container and it doesn't boil, but if you drop a fork in there the water explodes instantly.
For whatever reason a small amount of juice isn't turning into vapor fast enough and the transition is quick and violent instead of slower and more controlled.
From my experience it seems to happen more often when my wicks are over-saturated, so keeping a closer eye on your juice level while dripping might help. I've seen popping across all sorts of different coils (large/small diameter, compressed/spaced, etc) so if there's some correlation I haven't found it. Some juices tend to be worse than others, too.
I'm using a Kayfun Lite V2 Clone By EHPRO mounted on a Sigelei zmax usually at 9 watts. I always pulse burn the coil right after installing it on the platform. My coil is 10 wraps of 30g Kanthal at 1.5 ohms. It's wicking so good atm that I don't want to mess with lol. Infact it's just about perfect apart from that first initial pop everytime I pick it up....
I assumed you were using a dripper, my bad! That must be some good popping action to climb out of a Kayfun 
If you don't want to mess with your build an easy way to avoid getting hurt is to just press the button for a few seconds before you take your puff to pre-heat it a bit.
